✯ACHROMATISM:--
================
●achromatism is the phenomenon by virtue of which an object seen in white light through a lens would appear white i.e.there is no colour splitting
_____
●CONDITION:-
=============
To achieve achromatism ,all colours should be focused at a single point .To produce an achromat lens , a convex lens with positive chromatic aberration should be combined with a suitable concave lens of negative chromatic aberration so that total chromatic aberration is zero.

Condition for achromatism is that " The ratio of the dipersive power must be equal to the ratio of the focal length of the two lenses." i.e,
w1/w2 = f1/f2 where, w1 and w2 are the dispersive power of the two lenses and f1 and f2 are the focal lengths.
w1/w2 = f1/f2 where, w1 and w2 are the dispersive power of the two lenses and f1 and f2 are the focal lengths.
